LumenVox releases monthly versions of its products. When you first purchase a license for a product, you receive free upgrades for that license for one year. After that, software upgrades are covered as part of an annual maintenance contract. You may contact LumenVox Sales for more information about maintenance contracts.
You may always download the latest software that you have access to by logging into your account at and clicking "Your Software Downloads".
The Release Notes for a product document the changes in each version. Our recommendation is that you keep your product versions in synch; thus if you upgrade your Engine, you should also upgrade your License Server and Tuner.
When you upgrade your Tuner, you should also upgrade the Speech Engine. Uninstall the old versions of any LumenVox software using the Windows Add/Remove Programs control panel. First uninstall the Tuner, and then uninstall the License Server (and any optional components such as the MRCP Server) and finally uninstall the Engine.
Once the Engine has been uninstalled, reboot your machine and run the install for the latest version of the Engine, restart the machine, and then install the Tuner and any additional components (License Server, MRCP Server, etc.). You do not need to restart after installing these additional components.
